A school fantasy where you study sword and sorcery, discover your own divinity, and ascend to godhood.
About
Setting: Amagahara Academy, a prestigious school in modern Japan.
Those with supernatural powers—swordsmanship, sorcery, and special abilities—gather here to study combat, paranormal suppression, rescue, and mental/divine education alongside general subjects.
However, what is questioned at this academy is not simple strength.
Honing your skills and facing yourself, What do you desire? What do you protect? What do you reject? And what do you choose for yourself?
The answers eventually become "Divinity," creating the possibility of reaching Authority, Divine Domain—and even beyond.
Guest is a new student entering Amagahara Academy. Through classes, daily life with friends, practical exercises, paranormal incidents, and encounters with gods, you will shape your own unique way of being.
[How to Play] Basics: There is no set story or "correct" answer for Guest. You can act freely: attend classes, spend time with friends, train, get involved in incidents, run away, help, or refuse.
Growth: You don't grow just by defeating strong enemies. Along with skill mastery, how Guest thinks, chooses, and faces the consequences is reflected in their Divinity.
Abilities: You can use any skills you like, such as swordsmanship, sorcery, or supernatural abilities. Existing abilities may evolve into unique Authorities or Powers as they link with Guest's own values through growth.
Choices: The "correct" answer for good and evil is not fixed. You can follow or reject the opinions of others. What matters is "why you did it."
Daily Life: The story isn't just about combat. You can freely enjoy normal school life: classes, lunch, clubs, after-school time, and relationships.
[Authority Realms] First Realm (Technique): The stage where one can handle their skills safely and accurately. Second Realm (Spirit): The stage where one's own will and judgment appear in their skills. Third Realm (Divinity): The stage where values sprout as one's "Inherent Logic." Fourth Realm (Authority): The stage where one's Logic begins to affect the surrounding reality. Fifth Realm (Divine Domain): The stage where one establishes their Logic as a limited law of the world.
Realms are not a simple combat power ranking. Actual strength varies within the same realm depending on mana capacity, skills, compatibility, and experience.
[Realm Advancement Trials] Trials: Based on growth, trials are held to advance to the next realm.
First Realm: A confirmation of skill, control, and safety judgment, doubling as the entrance exam. Second Realm: Demonstrating one's own skill application through practical tasks with no set correct answer. Third Realm: Facing multiple conflicts and being questioned on what one values most. Fourth Realm: Controlling Authority while maintaining one's Logic, even in situations that contradict one's Divinity. Fifth Realm: Establishing one's own Divine Domain in a space cut off from external help.
It is rumored that something exists beyond the Fifth Realm, but details are not shared with general students.
[Divine Orientation] Divine Orientation: A guideline showing the direction in which a person's divinity is heading.
Examples: Freedom, Protection, Order, Inquiry, Creation, Empathy, Transcendence, Conflict, Self-Validation, etc.
This is not a profession or attribute, nor is it a fixed growth route.
For example, even with the same "Protection," the final Divinity and Authority will differ between one who heals wounds, one who blocks attacks, one who defeats enemies first, and one who creates a place where no one can be harmed.
Guest's Divine Orientation does not need to be decided from the start; it forms naturally from choices made during the story.
